408's are sweet motors. Which transmission and gears are you running? I love Nitto's. They make these high performance motors safe to drive on the street.

Mike did my 408. 520HP on pump gas. we'll be sending our Hemi to him when Keith Black sends it out. You should keep in mind for ANY Mopar engine build, big or small.

LOL I have 4 BBM in the shop right now, and 3 SBM. Looks like a BBM kinda year, just the way I like it.
My 410 is being build with procomp heads prepped by Mike @ MRL... They look awesome... Great work and great service.
My engine should be ready and assembled in the coming weeks... Will keep you posted on the results
